A 25.0 ml sample of a 0.100 M solution of aqueo us ammonia is titrated with a 0.125 M solution of HCI.
Ka * Kb = Kw = 1.0 X 10-14 A 25.0 ml sample of a 0.100 M solution of aqueo us ammonia is titrated with a 0.125 M solution of HCI. Calculate the pH of the solution after 0.00, 10.0, 20.0, 30.00, and 40.0 mL of acid have been added; Kb of NH3= 1.8 X 10-5 at 25 °C. Hint: First find the moles after each 10.00 ml of acid is added. Then find the concentration after equilibrium is reached.

Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of...
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...
